• How to find cause of main file system going to read only mode

  - by user606521

  Ubuntu 12.04 File system goes to readonly mode frequently. First of all I have read this question file system is going into read only mode frequently already. But I have to know if it's not caused by something else than dying hard drive. This is server provided by my client and I am just runing there some node.js workers + one node.js server and I am using mongodb. From time to time (every 20-50h) system suddenly makes filesystem read only, mongodb process fails (due read-only fs) and my node workers/server (which are started by forever) are just killed. Here is the log from dmesg - I can see there some errors and messages that FS is going to read-only, and there is also some JOURNAL error but I would like to find cause of those errors.. http://speedy.sh/Ux2VV/dmesg.log.txt edit smartctl -t long /dev/sda smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.5.0-23-generic] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net SMART support is: Unavailable - device lacks SMART capability.

• Safe mode boot with no change on screen but ongoing hard disk activity - why?

  - by omatai

  I have a machine with a dying hard drive - bad sectors are starting to multiply :-( The first sign (24 hours ago) was that it had an unmountable boot volume. At this time, I tried booting to safe mode with command prompt, which worked, after which I rebooted normally and ran a chkdsk. It has since been working as well as I could expect, but slowly getting less reliable. So I scheduled another chkdsk on both partitions (C: - boot, D: - data), having freed up a lot of space on both partitions to give Windows a little more scope for repairs (hopefully?). I then rebooted. On reboot, it protested about the unmountable boot volume again, so I booted to safe mode. I got the same list of drivers loaded as yesterday, and then no change to the screen for the past 2 hours. However, I see a flickering hard drive indicator light - not always on, but seldom ever off. What is happening? Is the chkdsk that runs in safe mode one which produces nothing on the screen and so chkdsk could be doing its thing... or is Windows still trying (but failing) to boot into Safe Mode?

• How to handle server failure in an n-tier architecture?

  - by andy

  Imagine I have an n-tier architecture in an auto-scaled cloud environment with say: a load balancer in a failover pair reverse proxy tier web app tier db tier Each tier needs to connect to the instances in the tier below. What are the standard ways of connecting tiers to make them resilient to failure of nodes in each tier? i.e. how does each tier get the IP addresses of each node in the tier below? For example if all reverse proxies should route traffic to all web app nodes, how could they be set up so that they don't send traffic to dead web app nodes, and so that when new web app nodes are brought online they can send traffic to it? I could run an agent that would update all the configs to all the nodes, but it seems inefficient. I could put an LB pair between each tier, so the tier above only needs to connect to the load balancers, but how do I handle the problem of the LBs dying? This just seems to shunt the problem of tier A needing to know the IPs of all nodes in tier B, to all nodes in tier A needing to know the IPs of all LBs between tiers A and B. For some applications, they can implement retry logic if they contact a node in the tier below that doesn't respond, but is there any way that some middleware could direct traffic to only live nodes in the following tier? If I was hosting on AWS I could use an ELB between tiers, but I want to know how I could achieve the same functionality myself. I've read (briefly) about heartbeat and keepalived - are these relevant here? What are the virtual IPs they talk about and how are they managed? Are there still single points of failure using them?

• Ctrl + 1 and Ctrl + 2 key combinations don't work

  - by musicfreak

  I noticed back in August (when I got StarCraft 2) that the key combinations Ctrl + 1 and Ctrl + 2 didn't work. I thought this was weird because Ctrl + 3 and all the other combinations worked fine (including Shift + 1, etc), so I didn't think much of it; I just shrugged it off as a SC2 bug. Now, 4 months later, I decided to play a completely unrelated game--Dawn of War 2--and noticed the same thing: those two specific key combinations don't work. To make sure I wasn't going insane, I tried it in Chrome and a couple other applications, and alas, it didn't work. I remember playing strategy games over the summer before StarCraft 2 and it worked fine. Any idea as to what went wrong? My keyboard, a Microsoft Wireless Keyboard 1000 (I know, insert Microsoft joke here), is a little over a year old, so I'm going to assume it's not dying until proven otherwise. Things I've tried ActiveHotkeys says the key combination is not a global hotkey. Tried another keyboard--still doesn't work. The key combinations do work in a virtual machine (tried with both Windows and Ubuntu as guests).

• How long will a USB key with an OS installed on it last?

  - by Xananax

  I've heard numerous times that installing an OS on a USB key is a bad thing to do, as USBs typically have a certain number of writes before dying, and installing an OS on it will wear it out (unless it's used sporadically for rescue purposes). Nonetheless, I am very tempted to install some flavour of Linux (Ubuntu or Arch, I haven't decided yet) on a small, transportable, USB Key. My problem is, although you read a lot that it's "bad", you are never told how bad. How long would it last (provided, say, a pc that is 24/7 on)? A month? A year? Five years? Is there recipes to make it last longer? Is there any reason beside weariness that should prevent me from attempting this? I mean, if it can be calculated, then I could theoretically shield myself by doing regular backups on another key when the deadline gets close (for example). Notes I am not talking of using a USB as a live CD, but actually installing the OS on it.) When I say "USB Key", I refer to the little USBs with a flash memory, not an external USB hard drive. For the curious, my reason is that I work in a lot of different places, on different PCs, and I have a very customized session, with my own WM, my own key bindings, my own scripts, , a selection of plugins for firefox and chrome, etc, and currently I am synchronizing all this through a mix of dropbox, git, and transporting files on USBs, and and it's becoming a chore. It would be much simpler for me to just plug the USB and mount the hard disk of the PC I am using and use it's processing power without actually needing to install any OS on it.

• Apache Process question about RAM usage

  - by Andrew Fashion

  So everytime I load a new page, I notice a new HTTPD process opens, every time I click a page, and each process says it's using anywhere from 2-4.5% of memory. Does that mean every single process is running at that time using 2-4% of RAM? It's a brand new server and I'm the only one on the server at the moment. Or does it mean all the other processes are dying, and only the new one is active. Because 4% of my 2048MB of RAM is already 82MB for just one process!?!? Let me know, because I am trying to determine what I need to beef my server up in order to handle high loads of traffic. I'm expect to get 20,000 uniques per day on launch. I am currently running a Dual Quad Xeon server, with only 2GB of ram, I will upgrade to 8GB or more shortly.

• SSH traffic over openvpn connection freezes when I cat a file

  - by user42055

  I have an openvpn (version 2.1_rc15 at both ends) connection setup between two gentoo boxes using shared keys. it works fine for the most part. I use mysql, http, ftp, scp over the vpn with no problems. But when I ssh from the client to the server over the vpn, weird things happen. I can login, i can execute some commands. But if i try to run an ncurses application like top, or i try to cat a file, the connection will stall and I'll have to sever the ssh session. I can, for example, execute "echo blah; echo .; echo blah" and it will output the three lines of text over the ssh session fine. But if i execute "cat /etc/motd" the session will freeze the moment I press enter. I compiled openvpn 2.1.1 on my mac and copied over my config directory from my gentoo client. The mac connected and ssh sessions worked fine without freezing. I then compiled it on my older gentoo box (2.6.26 kernel) which I am retiring due to a dying hard drive, and ssh over it also works perfectly. Why does it fail on my brand new gentoo box ? I've tried compiling three different kernels in case it was that, but other than that there should be no difference between my older and my newer gentoo boxes that I can think of. Any suggestions on what's wrong ?

• Mac OS Leopard: SyncServer process constantly using 100% CPU

  - by macca1

  I am running Leopard that I upgraded from Tiger. I've been noticing that every once in a while the SyncServer process starts up and eats up all the CPU. The fans will start going at full blast and the laptop will slow down to a crawl. I need to force quit the process from Activity Monitor to get it under control. It disappears for a while, but eventually gets started again. I do have an iphone as well that I sync so I'm wondering if syncServer might be an apple process checking for my phone plugged in. Edit: Tried iSync and the manual resetsync as suggested, but got this output: Vince-2:~ vince$ /System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl full 2010-03-12 08:03:50.230 perl[176:10b] SyncServer is unavailable: exception when connecting: connection timeout: did not receive reply PerlObjCBridge: NSException raised while sending reallyResetSyncData to NSObject object name: "ISyncServerUnavailableException" reason: "Can't connect to the sync server: NSPortTimeoutException: connection timeout: did not receive reply ((null))" userInfo: "" location: "/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl line 16" ** PerlObjCBridge: dying due to NSException Vince-2:~ vince$ And during that syncServer started spinning up 95-100% just like it always does.

• How to discover true identity of hard disk?

  - by F21

  I have 2 fake external hard drives that claim to have a storage capacity of 2TB. I pulled the enclosure apart and the hard drives seems to be refurbished ones with their labels replaced as Barracuda LP 2000 GB labels (the serial numbers on both labels are the same). Interestingly, one of the drives have 160G written on it with pencil. However, the counterfeiters seem to have done something to the firmware, because CrystalDiskInfo reports them as 2TB ST2000DL003 drives. I then delete the 1.81 TB partition in Windows disk management and tried to create a new one and format it. Once I get to this point, the drives would make some noise that is common to dying drives. I am not interested in using these drives for production, but I am interested in finding the true identity (manufacturer/serial number/model number, etc) and restoring it to their factory defaults with the right capacity. Can this be done without any special equipment? This would be an interesting learning exercise. Some pictures of the drives in question: Here are the screens from CrystalDiskInfo: Note the serial numbers are the same (these are 2 different drives!). How is this done? Did they have to tamper with the controller board? I would assume that changing the firmware doesn't change the serial number at all.

• Is UPS worthwhile for home equipment?

  - by Jon Skeet

  Over the years, I've had to throw away a quite a few bits of computing equipment (and the like): Several ADSL routers with odd symptoms (losing wireless connections, losing wired connections, DHCP failures, DNS symptoms etc) Two PVRs spontaneously rebooting and corrupting themselves (despite the best efforts of the community to diagnose and help) One external hard disk still claiming to function, but corrupting data One hard disk as part of a NAS raid array "going bad" (as far as the NAS was concerned) (This is in addition to various laptops and printers dying in ways unrelated to this question.) Obviously it'll be impossible to tell for sure from such a small amount of information, but might these be related to power issues? I don't currently have a UPS for any of this equipment. Everything on surge-protected gang sockets, but there's nothing to smooth a power cut. Is home UPS really viable and useful? I know there are some reasonably cheap UPSes on the market, but I don't know how useful they really are. I'm not interested in keeping my home network actually running during a power cut, but I'd like it to power down a bit more gracefully if the current situation is putting my hardware in jeopardy.

• Desktop PC does not power up on power button

  - by hIpPy

  When I press the power button on my desktop, it does not power up completely. Before I press the power button, I see lights on the motherboard. Everything is normal. On power button press, the fans on the cpu, graphics card and motherboard start to spin a little for a second or two and then they stop. No beeps during this process. It has been doing this for a while now but it used to start up after some trials. Once it starts up, I have NO issues at all like random shutdowns so it is not an issue with OS. I'm just guessing here but it seems as if the PSU (Antec TP2-550ATX) is dying out and does not have enough power now - just a guess. It's an old desktop assembled in 2005 but I have maintained it well. Any ideas? Please help. Thanks. Below is the complete configuration.

• Laptop battery holds charge, but won't charge any more.

  - by Jeff

  Ok, I'm sure I will need to replace either my battery or my AC adapter, but would rather not buy one if the other is the problem. My problem is. I have a Sager laptop that gets quite a bit of use. The charging has always been a little bit odd. If I was in the process of using it, it would charge just fine and stay On AC power. If I left it alone, however(power settings to ONLY turn off the monitor) in either Ubuntu or Windows 7 it decides that it didn't want to use AC power anymore and would just start draining the battery until it died. Now, suddenly, it won't charge at all. The capacity was great up to this point which happened in an instant. It will recognize the battery but won't see the AC power if plugged in while the battery is in. I can power up the laptop without the battery and it works fine. If I plug in the battery while powered up it will claim it's charging it, but it stays at the same percentage. If I unplug the power, it will switch over to Battery fine, but I have to power down and unplug the battery to get it back on AC power. I've had dying/dead batteries before but they typically won't hold a full charge anymore but it still winds up to 100% then drops quickly when unplugged. This seems more like a chip problem in the battery to me, but I'm not sure. Any ideas?

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• Network connection keeps dropping - bad hardware?

  - by Bill Sambrone

  Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

• Why is writing to my external hard drive slow, while benchmarks show fast writing?

  - by matix2267

  I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

• Graphite not running

  - by River

  I'm currently trying to install graphite 0.9.9 on a gentoo box using these instructions from the graphite wiki. Essentially, it fronts graphite using apache and mod_wsgi. Everything seems to have gone well, except that apache / the graphite webapp never seem to return a response to the web browser (the browser continuously waits to load the page). I've turned on the graphite debug info, but the only message in the log files is this, repeated over and over again in info.log (with the pid always changing): Thu Feb 23 01:59:38 2012 :: graphite.wsgi - pid 4810 - reloading search index These instructions have worked for me before to set up graphite on an Ubuntu machine. I suspect that mod_wsgi is dying, but I have confirmed that mod_wsgi works fine when not serving the graphite webapp. This is what my graphite.conf vhost file looks like: WSGISocketPrefix /etc/httpd/wsgi/ <VirtualHost *:80> ServerName # Server name DocumentRoot "/opt/graphite/webapp" ErrorLog /opt/graphite/storage/log/webapp/error.log CustomLog /opt/graphite/storage/log/webapp/access.log common # I've found that an equal number of processes & threads tends # to show the best performance for Graphite (ymmv).

• How to calibrate ASUS k52f battery on Ubuntu?

  - by cutalion

  I'm not sure if the problem is in software or my battery is dying, I'll move my question to another forum if it's not a SO question I have a problem with the battery on my laptop - ASUS K52F. It shows incorrect information about capacity. When I unplug the charger it can work some time, but then it will power off without any warnings. Sometimes it will power off right after I unplug the charger. Here is some info I could get: > uname -a Linux alligator 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux > acpi -i Battery 0: Charging, 99%, 18:25:15 until charged Battery 0: design capacity 5235 mAh, last full capacity 69964 mAh = 100% > cat /sys/class/power_supply/BAT0/uevent POWER_SUPPLY_NAME=BAT0 POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=10800000 POWER_SUPPLY_VOLTAGE_NOW=9246000 POWER_SUPPLY_POWER_NOW=176000 POWER_SUPPLY_ENERGY_FULL_DESIGN=**48400000** POWER_SUPPLY_ENERGY_FULL=**646822000** POWER_SUPPLY_ENERGY_NOW=**643588000** POWER_SUPPLY_MODEL_NAME=K52F-44 POWER_SUPPLY_MANUFACTURER=ASUSTek POWER_SUPPLY_SERIAL_NUMBER= I noticed, that POWER_SUPPLY_ENERGY_NOW and POWER_SUPPLY_ENERGY_FULL are greater than POWER_SUPPLY_ENERGY_FULL_DESIGN.

• Unusable network, packet losses between router and NIC

  - by KáGé

  I have this setup: Gigabyte P35-DS3P motherboard Asus NX1101 PCI network card (the one on the motherboard got fried a few years ago by a power surge) Asus RT-N16 router Windows 7 x64 I think the other specs are irrelevant here, but I'll post them if you say so. Until a week ago everything was fine, but then my network became unusable: websites start loading but timeout before anything would come through (true for the web interface of the router as well), I can't reach the computer from my notebook and Windows' ping utility measures a ~50% packet loss between the computer and the router. Pinging localhost is good. The router works completely fine when wired to my notebook. I also tested different ports on the router, different cables, different router and connecting directly to the modem, but it's still the same. Sometimes it works for a few minutes right after turning on the machine, but then it becomes crap again, but mostly it's useless from the start. I've tried updating the firmware on the router, updating the driver for the network card (after which I started getting BSoDs in every 15 minutes), reinstalling Windows, swapping to Fedora 15 but none of them changed anything. Does this mean that the network card is dying, or could it be something else? If it's the card, what model do you recommend as a replacement? (Could be PCI or PCI-Ex x1) Thanks for your help.

• configure a Macbook Pro to use external monitor at boot (Debian Linux)

  - by Eric

  In the spirit of reuse, I've installed Debian (version 6.0.5 "squeeze") on my wife’s old Macbook Pro (circa 2009 or so), to repurpose it for various tasks. The catch is the display is flaky. It will last a random amount of time, between 2 minutes and 2 hours, before freezing and graying out. This is a known issue with that generation of MBP. Fortunately it’s no problem for me, as I plan to use it with an external monitor anyway. Which brings us to the problem: How do I configure this thing to output to the external display by default, and hopefully disable the built-in LCD? The ideal solution would be to modify a setting in the EFI (BIOS), but I’m not holding out much hope for that. Next best thing would be a kernel option I can pass to the NVIDIA driver. What won’t work is a solution that doesn’t give me a display until X starts. I need to have console access, especially given that the built-in LCD is dying, and any day now might give out completely. So far I haven’t been able to find anything online. lspci says I’ve got an NVIDIA GeForce 9400M Help is much appreciated! Eric PS if this question is better suited to the Unix & Linux area, pls advise and I will move it.

• Merely installing PHP5 causes my AWS Ubuntu server to die minutes later from a massive CPU spike

  - by Mark Amery

  I have an AWS server with Ubuntu 11.04 as the OS that is running an Apache2 webserver (incidentally Python-based and using Django). We recently needed to add support for php5 to let us use a third party PHP library (incidentally for serving minified versions of js and css files). However, for no reason any of us can discern, if we simply run sudo apt-get install php5 on the server, then the install appears to finish successfully but, without us taking any further action (including not yet running sudo apt-get install libapache2-mod-php5, which I think would be the next step for us if everything worked), or actually running any PHP scripts on the server, a few minutes later the server becomes impossible to connect to, and looking at the 'Monitoring' tab for the server in the EC2 Management Console reveals that a while after the installation, CPU usage spikes to 100% and stays there permanently (until we reboot the server from the AWS Console). After rebooting, the server also reliably dies within a few (between 0 and 10) minutes. We restored the server to a pre-PHP state from an AMI Image, observed that it was stable, and then tried installing PHP5 again and observed the server die in exactly the same way, so we're pretty much certain that installing PHP5 is what causes the symptoms. What on earth could be causing this behaviour, and how can we get PHP installed on the server without it dying?

• PC dies when running at 100% CPU

  - by user155631

  I recently wrote some Java code to generate images of the Mandelbrot set (fractal). I made use of the new Fork/Join facility in Java 7 to run separate threads on all four cores (2 real, 2 virtual)simultaneously, using a large number of iterations for greater accuracy. The problem is, the process runs fine for about a minute, and then it's as if someone has pulled the plug and the PC just dies. I thought it must be the CPUs overheating, so I ran Real Temp to monitor the temperature. It's an Intel i3 processor. I can see the temperature creeping up to 70 degrees, and then it seems to level off there and run for about another 30 seconds before dying. According to Real Temp, there's still a gap of 35 degrees between the actual temperature and TJ max. I also tried disabling "CPU TM function" in the BIOS, but the problem still occurs. A colleague suggested that it might be a power supply problem, so I borrowed a more powerful PSU (can't remember what wattage it was, but it's higher than mine which is 500W). The exact same thing still happens though. Is anyone able to suggest what the problem might be, or what I can try next?

• Why is my cron daemon is being killed every few minutes?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6 x64 on an OpenVZ virtual machine. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has at least 800 MB of free memory, and cat /proc/loadavg returns 0.22 0.13 0.04 so resources shouldn't be the issue. With cron running, free -m reports: total used free shared buffers cached Mem: 1024 211 812 0 0 0 -/+ buffers/cache: 211 812 Swap: 0 0 0 I also tried removing and reinstalling the cron package using apt-get. Update: I initially thought the problem was a resource issues. I erased my entire VPS and started from a fresh Debian image. There is now nothing else running on the system, but even from a clean install my cron daemon is still being killed at random. What else should I check? How do I find out what's killing my crond?

• Windows based development environment: HyperV, VMWare, or VirtualBox on development machine?

  - by bleepzter

  I am a software engineer with a little bit of an informal "support" functionality... I am trying to figure out what is the best possible approach to employing virtualization technologies into our development process. Since the code we develop is server-centric, testing it often requires a VM with specific software requirements. I used to use VM Ware player (free version) to run my VM's until both of my laptops started exhibiting issues with corrupted windows 7 services and dying hard drives. All leads pointed to VMWare, which by the way seems to be a solid product if you pay for the Workstation edition ($300). On a side note, I have always been a fan of the Windows Server product line. I think it makes for one of the best development environments out there - it is highly scalable, highly reliable, and very efficient. So to be fair I replaced the drives of the laptops and installed Windows Server 2008R2, VS2010 Ultimate SP1, SQL Server 2008R2, TFS Server 2010 and all other tools and API's needed do do my work properly. So now I am stuck with a bunch of VMWare VMs. I don't want to repeat of what happened before, and I certainly don't want to bog down my machine with an inefficient hypervisor or services that are not needed. Futhermore the VMDK hard-disk format used by VMWare is not compatible with the VHD format of Hyper V. It is my understanding that converting from one format to the other can only happen by Microsoft System Center Virtual Machine which I have downloaded from MSDN and ready to install. I guess the question at this point is: Does SCVM run as another service in Windows? Is it a memory hog? What is a better virtualization technology - Hyper-V or Virtual Box in terms of efficiency ease of use and most importantly - memory footprint? (Keep in mind the development environment already has a ton of services running such as TFS Server, SQL Server, IIS, etc...) How would you advise to proceed at this point so that the VMs are still used in the test process? Thanks Martin

• What Media Extender / Centre Set up should I use?

  - by Bryn Hird

  I have installed cat6 throughout the house which I use for telephony and network. In my cellar I have a NAS Server, gigabit switch and I want to install a Media Centre to stream my video's, music, photo's and live TV (coax from the aerial to the cellar) over the cat6. Yeah I know I can get stuff on the internet but shared experience of watching TV as a family as it happens is a big plus for live TV. I'm aiming for 1080p. I want different users to be able to watch different channels. Max users = 4. I've played a little with Windows Media Centre, works fine with live TV. Likewise I have XBMC up and running with live TV. The issue I have is what do I put near the TV. I'd like a consistent user interface (grandma and the the other technophobes in the house are continually pestering me on how to use different TVs, change channel, inputs etc.) so a key part of this for me is to make the user experience the same and simple i.e. no keyboards / PCs hanging around the TV. I've just bought a Linksys DMA 2200 to test the Windows Media Centre, but obviously off eBay as they're a dying breed. And with Windows Media Centre removed from Microsoft plans such devices will get rarer. And as for 1080p, think I can forget it with that set up. I have tested XBOX 360, also works but ditto on Microsoft plans for WMC. I was thinking of a WD Live TV to test the XMBC setup. Now to the question. Any advice on Media Centre / Extender setups that will do the job as above and have some degree of futureproofing (building my own with my Raspberry PI is a last resort). I'd like to understand the standards involved in the futureproofing if anyone knows (DNLA, RVU etc.).

• Determining physical location of data on a disc

  - by Synetech

  Does anybody know of a way to find out where, physically on a CD or DVD a given piece of data would be located? I am trying to watch a DVD at the moment, and am about half-way through, but it keeps dying at a specific spot in the film, presumably because of a scratch. I have a repair kit, but I don’t know where to focus my repair because there are several scuffs and scratches on the disc and I have no way of knowing which one is causing the issue. Obviously, cleaning all of them is inadvisable because not only does it waste the consumable materials in the kit, but not all of them are a problem, and by working them, some may become unreadable. Moreover, just because I am half-way through the movie does not mean that it would be half-way from the hub to the edge for several reasons: Discs have more data towards the outer edge than the inner edge (circles are more mathematically complicated than rectangles) The disc is not completely filled up (and even if it were, the movie itself would be be using it all, there are extras and such) Because in this particular case it is a commercial DVD, it is also dual-layer which further complicates manual determination As such, I am trying to find a program that can let me identify a file (or part thereof), cluster, etc. and show me a picture of where on the CD/DVD it would be located. That way, I can look at the disc and fix any scratches that correspond to that distance from the hub. For example, the image below might indicate where on a disc a couple of files or range of clusters would be located, so by looking for anomalies in those areas (rotating as necessary), the correct one can be identified. I’m sure it can be done since at least one form of copy protection (DPM) uses it and DVD-lab Pro includes a “DVD Topology” feature to do this.
